[Plugin: W3 Total Cache] Export Media Library to CDN Skips Random Items

Using WordPress 3.0.5 w/ W3TC 0.9.1.4b (Dev Latested as of 3/1/11 – needed the nginx support)

Problem:
Importing 5 year old site, roughly 7200 images, to Amazon S3/CloudFront configured as an Origin Push.

After the import has completed (I have run it 3x to make sure it wasn’t just skipping on accident) there are random, small (file-size and dimensionally) images that are skipped from the CDN import that now result in broken images.

Example page:
http://www.thebuzzmedia.com/2007/05/

Scroll down to “Great Earings for Nerdy Girls”, this is the missing referenced image:
http://cdn.thebuzzmedia.com/wp-content/uploads/2007/05/head_earings-100×100.jpg

which is sourced from here:
http://thebuzzmedia.com/wp-content/uploads/2007/05/head_earings-100×100.jpg

NOTE: The “access denied” is a red-herring, using the S3 admin panel I have confirmed that file does not exist in the S3 bucket.

You’ll notice the other small thumbnails from many of the other posts copied just fine. Even though they look to be roughly the same size.

Another example where the original image from the post itself is missing is this story:
http://www.thebuzzmedia.com/smugmug-rolls-out-islands-feature/

referencing this image:
http://cdn.thebuzzmedia.com/wp-content/uploads/2007/05/smug_mug_islands_settings.thumbnail.gif

which is sourced from here:
http://thebuzzmedia.com/wp-content/uploads/2007/05/smug_mug_islands_settings.thumbnail.gif

And most notable is the missing favicon.png that didn’t copy over either.

Is there some implied file-size filter running on W3TC’s sync code? The behavior I’m seeing (no original/large images missing, but random tiny images like GIFs and small PNGs and JPGs are missing).

I can’t imagine such an arbitrary filter would be put into the code, but the behavior suggests “yes”; anybody have any ideas?
